因此,我只是将我的应用程序转移到另一台笔记本电脑上,并且在尝试生成此错误时出现提示。请帮忙。我需要更改什么?

ids.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <item name="timebar" type="id">Time</item>
    <item name="textClock" type="id">textClock</item>
</resources>

2 个答案:

答案 0 :(得分:1)

应该是:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <item name="timebar" type="id"/>
    <item name="textClock" type="id"/>
</resources>

裁判是here

答案 1 :(得分:1)

在资源文件上,删除结束标记和正文,即删除“ tv_deviceName”

  <item type="id" name="button_ok">tv_deviceName</item>

Id应如下所示

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <item type="id" name="button_ok" />
    <item type="id" name="dialog_exit" />
</resources>

然后,此布局代码段使用Button小部件的“ button_ok” ID:

<Button android:id="@id/button_ok"
    .... />

请注意,android:id值未在ID引用中包含加号,因为ID已存在(如上述ids.xml示例中所定义)。 (当您使用加号为android:id =“ @ + id / name”格式指定XML资源的ID时,这意味着“名称” ID不存在,应该创建。)

作为另一个示例,以下代码段使用“ dialog_exit” ID作为对话框的唯一标识符:

showDialog(R.id.dialog_exit);
